System Workbench for STM32

Hi Udibit,

It happend beacuse your example use some files to compile according with IAR compiler.

The __packed attribute is kinda different on GCC compiler, as described here:

To solve this, you can go to:

Project Proprieties -> C/C++ General -> Paths and Symbols -> (TAB) Symbols

and press to add a symbol, and:

name: __packed
value: attribute packed

You should do it to __weak too

I saw this on a generated project from STM32CubeMX.
